No. 10,057. Patented Sept. 27. 1853.

UNITED STATES PATENT OFIG DANIEL P. FALES, OF WEST POULTNEY, VERMONT.

CAR-WHEEL.

Specification of Letters Patent No. 10,057, dated September 2'7, 1853.

To all whom it may concern:

Be it known that I, DANIEL P. FALES, of West Poultney, in the county of Butland and State of Vermont, have invented a new and Improved Car-I/Vheel; and I do hereby declare that the following is a full and eX- act description thereof, reference being had to the accompanying drawings, making a part of this specification, Figure 1 being a side view; Fig. 2, a section in the line a a of Fig. 1; Fig. 8, a section in the line b b, and Fig. 4 a section in the line 0 o of the same figure.

Similar letters refer to corresponding parts in all the figures.

The hub and rim of my improved car wheel, are united on one side by a main or thick face plate E, which has an undulating curve; commencing at the hub it first curves inwardly, then outwardly to a point about half way between the hub and rim and then inwardly until it unites with or expands into the rim. On the other side, the hub, rim and the aforesaid face plate, are all combined with each other by means of an undulating thin auxiliary plate B, in the manner represented by the drawings and hereinafter set forth. The undulations (Z, (Z, of the plate B, curve inwardly in the direction of their cross sections-as shown in Fig. l-and in their longitudinal direction commencingat the rim, they incline outwardly untll within a short distance of the hub, where they terminate in outward curves which join them to the hub. Between the undulations at, (Z, are the undulations c, e, which are of the following shape; to wit,commencing at the hub, they first curve inwardly a short distance, then curve outwardly and inwardly, and unite with the face plate E, about midway between the hub and rim. This arrangement of the respective parts of my improved car wheel has the following advantages; viz. when the core is in continuous contact with the inner surface of the rim of the wheel, it is found that the process of chillin its outer periphery, gives to its inner peripIiery an open and spongy character, which causes the wheel to first give way and open at the center of the rim. In my wheel, the core forms only that portion of the inner periphery of the rim which is opposite the extremity of the spaces between the face plate E and the undulations (Z, (l, of the back plate B. The other portions of the rim therefore, are more compact on their inner surface, and serve to give a greater degree of strength to the rim. The undulations of the plate B, by which it is united to alternate portions of the rim, and alternately to central portions of the face plate E, by a series of outward, inward, and radial curves, enables it at the same time to support the rim and the face plate in the most efficient manner when in use; and also to guard against injury from irregular shrinkage during the process of cooling.

I am aware that car wheels composed of two side plates of different shape cast in one piece with the hub and rim in which the rear plate is made to combine the inner end of the hub with the face plate and with alternate portions of the inner edge of the rim, have been made by Bristol and Jackson, and therefore I do not claim to be the }inventor of this description of car wheels;

What I do claim and desire to secure by Letters Patent, is

My improved car wheel, composed of the face plate E, which curves first inward, then outward, and then inward, and expands into the rim, and the rear plate B, which by the series of curves represented in Figs. 2, 3, and l, combines the inner end of the hub with the face plate and with alternate portions of the inner edge of the rim, substan-- tially as herein set forth.

The above specification of my improved car wheel signed this 3rd day of Sept. 1852.
